MOTU tells us that they are now shipping the UltraLite-mk4, a half-rack 18-input, 22-output audio interface with best-in-class analog audio quality, DSP mixing, new optimized low-latency drivers and wireless control for mobile audio recording and mixing.

Jim Cooper, MOTU Director of Marketing, said, "The UltraLite-mk4 delivers an impressive combination of superb audio quality, industry-leading latency performance and extensive connectivity."

Here's the details in MOTU's own words...

The latest in MOTU's award-winning UltraLite series, the UltraLite-mk4 provides a total of 40 simultaneous I/O channels, including two front-panel XLR/TRS combo-style mic/guitar inputs with preamps, 6 x 10 balanced quarter-inch analog I/O, 8-channel ADAT optical (switchable to stereo TOSLink), stereo RCA S/PDIF I/O and MIDI in/out jacks, all housed in a compact, rugged aluminum alloy chassis that slides easily into a backpack.

The balanced, DC-coupled analog outputs achieve a measured dynamic range of 117 dB, rivaling the audio quality of interfaces at much higher price points.

New, optimized drivers for Mac and Windows deliver ultra-low latency performance, with roundtrip latency (RTL) as low as 1.83 ms (with a 32-sample host buffer setting, operating at 96 kHz).

Expanded DSP doubles the available processing power (from the mk3) for the redesigned console-style mixer, which provides 48 inputs, 12 stereo busses and 32-bit floating point effects processing, including modeled analog EQ, vintage compression and classic reverb. Matrix routing lets users quickly patch ins to outs, or split inputs to multiple destinations. Users can take the UltraLite-mk4 on the go as a mobile mixer, controlling everything wirelessly from innovative web app software running on their iPad™, iPhone™, tablet, smartphone and laptop.

The UltraLite-mk4 connects to a computer through hi-speed USB 2.0 (audio class compliant, compatible with USB 3.0 and iOS) and records at sample rates up to 192 kHz.

Like all MOTU audio interfaces, the UltraLite-mk4 includes a suite of audio analysis tools, including a full-screen real-time FFT display, spectrogram "waterfall" display, full-featured oscilloscope, X-Y plot and phase analyzer.
